Fixed Pattern Damage

Fixed Pattern Damage is a measurement of damage to the finder pattern
where modulation scores for the fixed pattern portions of 2D matrix barcodes
are degraded. This failure may be caused by physical damage to the code
such as a mark or scuff or may be due to printing errors such as a bad print
head.
The ODV-2D will fail any barcode with a fixed pattern damage at or below
the value set in this menu, regardless of overall grade.

Axial Non-Uniformity
Axial Non-Uniformity is a measurement of the uneven scaling of symbol
obtained by measuring the module centers in both the X and Y axis. Low
axial non-uniformity grades may be caused by software errors in code
generation or print speed variation during printing.
The ODV-2D will fail any barcode with an axial non-uniformity at or below the
value set in this menu, regardless of overall grade.

Grid Non-Uniformity
Grid Non-Uniformity is a measurement of deviation of the scanned grid from
the ideal grid (deviation of measured grid intersection positions of a 2D ma-
trix barcode from ideal theoretical positions). Low grid non-uniformity grades
may be caused by media slippage during printing.
The ODV-2D will fail any barcode with grid non-uniformity at or below the
value set in this menu, regardless of overall grade.
